An awesome and easy to use piece of kit
For ULP Weather Logger with ESP8266 (WiFi, IoT)
The instructions that came with this kit made it really easy to flash with an FTDI connector. The only issue I have had so far, is that the instructions did not include the details to put in the Arduino software. This may have caused me some issues, although it's possible I set some parameters incorrectly. I contacted the supplier, and he got back to me quickly with the correct parameters and some hints on debugging (and where my issue may have been). I set it up for a new network, used the correct parameters, and everything worked fine. The included Blynk code is well written and a useful basis for whatever you want to do.
The hardware is very energy efficient, can come with everything pre-soldered and ready to go, and has a wide range of sensors on board. Fantastic work! I will be ordering more to replace some old temperature/humidity sensors that I have at work.
In case you are unsure about the Arduino software settings, I used these ones: Board: Generic ESP8266 Module, Flash Mode: QIO, Flash Size: 1M (NO SPIFFS), Debug Port: Disabled, Debug level: None, IwIP: Low Memory V2, Reset Method: None, Crystal Frequency: 26Mhz, Flash Frequency: 40Mhz, CPU Frequency: 80Mhz, Builtin LED: 2, Upload Speed: 115200, Erase Flash: Only Sketch.
